Utility model content

Therefore, in view of the above-mentioned problems, the utility model proposes a heat-sealed heat-cut suture bridge with a simple structure, capable of effectively realizing cutting and suturing, and running stably.

In order to achieve the above purpose, the utility model adopts the following technical solutions: a new type of heat-sealed hot-cut suture bridge, including a fuse joint seat, a sliding seat for wrapping the packaging film, and fuse wires are arranged side by side on the fuse joint seat For the hot-melt suture strip, an arc-shaped protrusion is provided on the sliding seat corresponding to the fuse wire, and a heat-resistant cushion is provided on the sliding seat corresponding to the hot-melt suture strip.

Further, the outer layer of the arc-shaped protrusion is wrapped with a layer of silica gel to prevent the packaging film from sticking to the arc-shaped protrusion.

Further, the hot-melt joint seat is provided with a temperature-resistant film covering the fuse wire and the hot-melt seam strip.

Further, the thickness of the heat-resistant cushion is greater than that of the arc-shaped protrusion, and the difference is less than 3mm.

Further, a heat insulation board is arranged on the fuse joint seat, and the fuse wire and the hot-melt seam strip are respectively arranged on the heat insulation board.

By adopting the foregoing technical scheme, the beneficial effect of the utility model is that the novel heat-seal hot-cut suture bridge realizes cutting through the fuse wire, and realizes joining with the hot-melt suture strip, both of which are connected with the power supply, and pass the pulsed current, thereby Instantaneous heating can be realized, so as to realize cutting and joining. The difference between the fuse wire and the hot-melt suture strip is that the width of the two is different. The preferred width of the fuse wire is 0.3mm-1mm, and the best is 0.5mm. Hot-melt suture The preferred width range of the strip is 3mm to 10mm, the best is 5mm, and the current can be adjusted to realize that the heating of the fuse is greater than that of the hot-melt suture strip, or through the selection of materials, the temperature of the fuse can be reduced when the current of the same size is connected. The heat generation is greater than that of the hot-melt suture strip, and there is an arc-shaped protrusion on the sliding seat, which can realize effective line contact with the fuse wire, and can also be used as the contact surface for packaging film transportation when it is not blown. The cushion can effectively realize the full contact between the packaging film and the hot-melt suture strip, so as to achieve the effect of uniform suture; further, the outer layer of the curved convex is wrapped with a layer of silicone, which can effectively prevent the packaging film from sticking to the arc On the protrusion; further, the heat-melt joint seat is provided with a temperature-resistant film covering the fuse wire and the heat-melt seam strip, which can effectively prevent the packaging film from sticking to the fuse wire or the heat-melt seam strip; further, the temperature-resistant The thickness of the soft pad is greater than the thickness of the arc-shaped protrusion, and the difference is less than 3mm, which is more conducive to the arc-shaped protrusion pressing the fuse, thereby achieving full blown; further, the fuse joint seat is provided with a heat shield , the fuse wire and the hot-melt suture strip are respectively arranged on the heat insulation board, so as to perform effective heat insulation.

detailed description

The utility model is further described now in conjunction with accompanying drawing and specific embodiment.

Referring to Fig. 1, this embodiment provides a novel heat-sealing hot-cut suture bridge, which includes a fuse joint seat 1 and a slide seat 2 for wrapping the packaging film. The fuse joint seat 1 is provided with a heat shield 3, so A fuse 4 and a hot-melt suture strip 5 are arranged side by side on the heat insulating board 3, and an arc-shaped protrusion 6 is arranged on the position corresponding to the fuse 4 on the sliding seat 2, and the thermal fuse 4 is connected to the sliding seat 2. A temperature-resistant soft pad 7 is provided at the corresponding position of the 5 welded joints, and the outer layer of the arc-shaped protrusion 6 is wrapped with a layer of silica gel 8 to prevent the packaging film from sticking to the arc-shaped protrusion 6 . The hot-melt joint seat 1 is provided with a heat-resistant film 9 covering the fuse wire 4 and the hot-melt seam strip 5 .
